解决No Certificates are available

今天在做苹果推送的时候遇到了这个问题，我明明是有证书的-------但一直解决不了

最后在stackoverflow的一个回答里找到答案了-----其实就是需要先做一个不是apn的证书出来

stackoverflow原地址：点击打开链接

解决我问题的回答是这个：

ok i had the same problem but basically you just have to go back and create a standard iOS development certificate. Don't click the APN certificate. It worked for me
